Unbelievable tones..From an app on a phone?

I am amazed with the whole package here. I drive a truck long distance, and before now, resources for tone and ways to practice shredding guitar was very very limited. With Jamup Pro XT , not only can I keep my chops up, but create with unlimited possibilities and with tone from the bunk of my truck equivalent to my mesa 4x12 cabs and rack preamps at home. My drummer records grooves and loads them to itunes from 2,000 miles away, I then import them from itunes to the 8 track in my truck on my phone, lay down rhythm tracks, overdub screaming solos, and export them to itunes. Holy s#|t how freakin awesome is that? I recently tackled a cover song, The Hunter by Dokken as George Lynch has always been a favorite. I used the Marshall JCM800 amp model, tape Echoplex, boss chorus, eq, and tube driver, and achieved a tone so close people can't tell it's not George's studio tone. Amazing Amazing tool in the form of an app. Thank you guys for making music an important part of therapy for my soul again..
